England's reply started well as Edwards and Arran Brindle (21) put on 63 for the first wicket. With Sarah Taylor (22), Edwards added another 36 before the innings began to unravel.

Jonassen removed Lydia Greenway for one and then Osborne had Edwards caught by Fields to spark the collapse.

Heather Knight's 25 was the only other innings of substance and she was the next to go, followed by Marsh (3), Jenny Gunn (5), Tamsin Beaumont (9), Brunt (3) and Holly Colvin (3) as Australia finished off the job in ruthless fashion.

With two points available for a win in all of the five remaining games (two ODIs and three Twenty20 Internationals), England have opportunities to hit back but Australia need only nine points to retain the Ashes whereas England need 10 to regain them.
